Car Stall problems of the 2016 GMC Yukon

Bought SUV 6/25/2016 the same weekend the engine turns off after a left or right turn :it has happened 3 times so far. 4 week old 2016 Yukon denali xl, has stalled 3 times in last 4 weeks, engine cuts off after a left or a right turn only after a short drive out of home. The SUV has to be restarted! could have easily had an accident or worse. I took it to the westpoint GMC dealer, 3 times. 1st two times, all of service deptartment could not diagnose the problem. Today, after a stall, I called onstar, who ran a diagnostics test,but onstar found nothing of value , I left it at dealership and contacted district mgr. Matt tillson . I was told that they would escalate the issue. I did tell dealer that GMC and dealership would be at fault if vehicle is involved in an accident and stalls nor stops while I am driving. I did not want the vehicle back without the problem having been fixed. Its day 6 today. I need to make it absolutely clear, I will not take the vehicle back untill the problem has been diagnosed, and fixed. I do not want me or my family or gm service employee injured, or worse, or to be involved with a possible accident in my GMC Yukon denali xl. A field service engineer should have been on this case already ! will it take an accident, or injury before someone gets assigned?.

On February 27, 2016 purchased a brand new GMC, Yukon sle, 2016, and VIN# (1gks2fkc3gr170330). On February 28 2016 I noticed a rumble in the engine, a vibration of the entire vehicle, a loud hissing from under the vehicle and an extreme jerk when traveling uphill.
